NEUTRINO BEAMS AT CERN AND FERMILAB

The CERN SPS West Area Neutrino Facility (WANF) is today the most copi ous source of high energy neutrinos, presently exploited by the CHORUS and NOMAD experiments searching for nu(mu) to nu(tau) oscillation ove r a short (1 Km) baseline. A New (or Next) Neutrino Facility (NNF) is however under active study with the purpose of serving experiments hou sed in the Gran Sasso Laboratory and searching for nu oscillation over a long (730 Km) baseline. A similar nu facility (NuMI) has now been p lanned at Fermilab for several years. Its design exploits the high int ensities that will be provided at the new Fermilab Main Injector (MI). Both a short baseline and long baseline (in the Soudan mine 732 Km fr om the source) experimental stations are foreseen. The two new facilit ies are expected to operate at about the same date (2002 or so). The m ain features of the three beam lines are summarized. Similarities, dif ferences and relative merits are briefly discussed.
